The diminutive ancestors of men (and hobbits, and elves, and dwarves?) watch in horror as a Sauroniops hidden in the vegetation watches them back. Sauroniops is one of those frustrating dinos named and described from pathetically fragmentary remains, so we really have no idea what they looked like; but its name, meaning "eye of Sauron", was too epic to be ignored.Its remains were found in Morocco and it coexisted with Spinosaurus and Carcharodontosaurus.

But, as far as i've read about this guy, i wouldn't be surprised if he'd turn out to be just a big Carcarodontosaurus (we just have a postorbital which looks veeeery similar to Carcha's ones only slightly larger, for Smaug's sake!)...

Three Rings for the Maniraptor-Kings under the sky,Seven for the Ankylosaurid-lords in their halls of stone,Nine for puny mammals doomed to die,One for Sauroniops on his dark throneIn the Land of Morocco where the Shadows lie.One Ring to rule them all, One Ring to find them,One Ring to bring them all and in the darkness bind themIn the Land of Morocco where the Shadows lie.
